Navigate to the Boxee apps directory in a terminal. Then run:
git clone git://github.com/tommysqueak/Boxee-Boilerplate.git developer-id.your-app-id
The developer-id should be your unique prefix for you or your company. Mine is 'greatboxee'.
Then open up the descriptor.xml (located in the developer-id.your-app-id directory) in your editor of choice and fill in the blanks. Open Boxee and check it runs ok. Make a kick-ass app.
If you're using Git for source control, rename example.gitignore to .gitignore
You'll need Ruby, Rake and bundler installed (gem install bundler, gem install rake).
Open build/environments.yml and fill in the blanks.
From a terminal:
cd build
bundle install
rake
This will create 2 packaged apps. One for deployment to your staging server/repository and one for the official Boxee app library.
